GEORGE TUPPER BROWN, OF BALTIMORE, MARYLAND, ASSIGNOR OF ONE- I-IALF TOTHE MCCORMICK A; COMPANY, OF SAME PLACE.

LAM P-BURNER.

SPECIFICATION forming part of Letters Patent No. 576,025, dated January26, 1897.

Application filed October 6, 1896- T 0 all whom. it may concern:

Be it known that I, GEORGE TUPPER BROWN, of Baltimore, in the State ofMaryland, have invented certain new and useful Improvements inLamp-Burners; and I hereby declare that the following is a full, clear,and exact description thereof, reference being had to the accompanyingdrawings, which form part of this specification.

This invention is an improvement in burners for lamps; and it consistsin a combined lamp -burner, chimney-holder, and wickraiser combined witha plug attachment of cork or other suitable material adapted to fit inthe neck of abottle or other oil-containing vessel and'hold the burnerin place instead of the more complicated fastenin gs commonly used. Inmy burner the base plate, the spring prongs or fingers forming thechimney-holder, and the bearings to support and hold the wick-raiser inplace are all formed out of one piece of sheet metal by stamping. Thewick-holder is a single tube extending perpendicularly through thebase-plate, the

portion thereof below the base-plate being fitted in the plug. Certainother peculiarities of the device will be hereinafter described, and thedrawings illustrate the burner clearly.

Referring to said drawings, Figure l is a side vview of a lamp having myburner applied. Fig. 2 is a view of the burner detached. Fig. 3 is avertical section through the burn er. Fig. 4 is a plan view. Fig. 5 is avertical sectional View illustratinga slight modification of the burner.

The circular baseplate A has a shallow flange a on its edge, from whichflange rises a series of fingers B, which constitute the chimney seatand clam p. Each of said fingers, as shown in Figs. 1 to 4, has ahorizontal groove 1) in its inner face about midway of its length, saidgroove being preferably formed by bending the fingers, as indicated inthe drawings, and the upper ends of the fingers are contracted andslightly curved outwardly, as shown. In two of the fingers B areperforations 19 for the reception of the wick-raiser rod 0, which isprovided with a serrated wickraiser c and the usual handpiece 0. Thewick-raiser 0 partially projects into the central wick-tube D andthereby keeps rod C $erial No. 608,056. (No modelJ from slippinglongitudinally out of its bearings.

The wick-tube is preferably a short piece of round tubing extendingthrough a central opening in the base-plate and fastened thereto bysolder.

The tube projects gage the wick.

Fitted on the portion of the tube below the base-plate is a plug E,preferably of cork or compressible material,wl1ich may be fasten ed tothe tube or base-plate, or both, by suitable cement or otherwise, and isadapted to fit tightly in the neck of an oil-containing vessel, such asa bottle or globe, and thus secure the burner in position. This plug hasa vent e in its side to allow the escape of air when the burner isfitted to the vessel, and to allow the escape of gases, if any aregenerated in the vessel, so that the oil will not be forced up chimneyon the burner.

No screws are necessary on my burner, however, for the fingers are madesufficiently resilient to bite the edge of the chimney and hold it inplace, the grooves 12 forming both a seat and a clamp for the chimney.

It Will be observed that the chimney-seat is slightly above thewick-raiser rod, so that the chimney does not rest upon the rod, but isentirely supported by the fingers, and a space is left between thefingers and below the chimney for the admission of air to supportcombustion.

In the modification shown in Fig. 5 the fingers are shaped to hold achimney with a straight vertical flange onits bottom, like the ordinarylamp-chimneys now most generally used.

I prefer the other form of chimney,

however, as the fingers clamp it in position sothat it cannot tilt overor drop off the burner.

The extreme simplicity of my invention is The base-plate and one of itschief merits.

fingers are formed out of one piece of metal by an economical stampingprocess. The wick-tube can be rolled or drawn, and the wipk-raiser androd are the simplest obtainab e.

It is not upon the small number of parts that I lay stress, but upon thesimplicity of their construction and their novel peculiarities.

Having thus described my invention, what I therefore claim as new, anddesire to secure by Letters Patent thereon, is

1. The herein-described lamp-burner and chimney-holder, consisting ofthe base-plate provided with upstanding fingers on its periphery bent ata point above the base-plate so as to form both a chimney seat and clampfor supporting and retaining the chimney above the base-plate; combinedwith a wickraiser rod journaled in two of the spring-fingers whichsupport the chimney,and the wickraiser on said rod, substantially as andfor the purpose described.

2. The herein-described lamp-burner and chimney-holder, consisting ofthe base-plate provided with upstanding fingers on its periphery bent ata pointabove the base-plate so as to form both achimney-seat and clampfor supportingand retaining the chimney above the base-plate; combinedwith a wick-raiser rod journaled in two of the spring-fingers whichsupport the chimney, and the Wickraiser on said rod; and a plugsurrounding the wick-tube below the base-plate, adapted to fit into theneck of a bottle or other oil-receptacle and secure the burner thereto,all

substantially as and for the purpose set forth.
